  • The quaternary ZrCrAIN nanocomposite thin films are synthesized by Closed-Field Unbalanced Magnetron Sputtering (CFUBMS). Microstructure and mechanical properties of ZrCrAIN nanocomposite thin films are studied. Grain refinement of ZrCrAIN nanocomposite thin film is occurred by controlling $N_{2}$ partial pressure. Maximum hardness value according to the various $N_{2}$ partial pressures is obtained at 45 GPa. It is also conformed that critical value of the grain size (d) needs to achieve the maximum hardness.

  • Quaternary TiZrAlN nanocomposite thin films were synthesized by Closed-Field Unbalanced Magnetron Sputtering (CFUBMS), and their microstructure and mechanical characteristics were examined. The grain refinement of the TiZrAlN nanocomposite thin films was controlled by adjusting the $N_2$ partial pressure. The hardness of the film varied with the $N_2$ partial pressure and the maximum value was obtained approximately 47 GPa. It was also confirmed that there is a critical value of the grain size($d_c$) to need maximum hardness.

  • Quaternary TiZrAlN nanocomposite thin films with a composition of 20.7Ti-22.2Zr-2.7Al-54.4N (at.%) were deposited by the closed-field unbalanced magnetron sputtering (CFUBMS) method and oxidized in air at temperatures between 500 and $700^{\circ}C$. The oxides formed were $TiO_2$, $ZrO_2$, and $Al_2O_3$. The films had inferior oxidation resistance because the amounts of $ZrO_2$ and $TiO_2$ were large while the amount of $Al_2O_3$ was small. The oxidation progressed primarily by the inward diffusion of oxygen and the outward diffusion of nitrogen.
